COMBINATION SCREEN AND STORM DOOR.

Application filed June 7, 1918.

To all whom it may concern:

Be it known that I, MARTIN H. Or'ro, a citizen of the United States,resident of Minneapolis, county of Hennepin, State of Minnesota, haveinvented certain new and useful Improvements in Combination Screen andStorm Doors, of which the following is a specification.

The object of my invention is to provide improved means for fastening ascreen or storm sash in a door to the end that the door can be easilyand quickly converted from a storm to a screen door or vice versa.

A further object is to provide a fastening means for the screen andstorm sash which will hold the sash securely, eliminate all danger ofrattling and at the same time effectually close the joint between thesash and the stiles of the door.

The invention consists generally in various constructions andcombinations, all as here inafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure l is an elevation of a door with my invention applied thereto,

Fig. 2 is a sectional view through the door, showing the manner ofmounting the fastening device therein,

Fig. 3 is a side view showing the manner of grooving the door stile andthe sash to receive the fastening device,

Fig. 4 is a perspective view of the fastening device taken apart.

In the drawings, 2 represents a door having stiles 3. Openings 4 and 5are provided in the door where the panels are usually arranged and Ihave shown an opening at the bot-tom as well as the top though, ofcourse, the one at the bottom may be omitted, if preferred, and probablywould be, as there would usually be no necessity for a transparentbottom panel in the storm door, though frequently desirable wherescreens are substituted for the glass panels. However, this isunimportant, as my invention is applicable to any style of doorregardless of how many removable panels may be provided. The stiles arerabbeted as at 6 to form seats for the sash 7 which may contain eitherglass or a wire mesh, it being only necessary to substitute one for theother to adapt the door for cold or warm weather.

Various devices have been provided for Specification of Letters Patent.

Serial No. 238,649.

fastening these interchangeable panels or conspicuous, the only elementsin view being the ornamental head of the screw on the inside of the doorand the pocket into which this screw is inserted. There are, as shown,preferably four of these fastening devices with each panel, one at eachcorner, and the sash is provided with grooves 8 in the edges andcorresponding grooves 9 are provided in the stiles of the door oppositethe grooves S. I also provide similar grooves 10 in the stiles inparallel relation with the grooves 9 and separated therefrom by a narrowweb 11 which is sufficiently flexible to yield under pressure of thefastening device. A plate 12 has a key-hole slot 13 therein at a pointmidway between its ends, which registers withan opening 14; extendingthrough the stiles of the door transversely of the grooves 9 and 10 andthe web 11. At one end of the bore of this opening is a bushing 15,suitably ornamented and concealing the edge of the opening on theinside. At the other end of the opening on the outside is a plug 16 witha rounded ornamental outer end. A screw 17 fits within the bushing 15and has lugs 18 formed thereon to fit into the ends of the keyhole slot13 to turn the plate 12 when the screw is rotated and the plug 16 hassimilar lugs fitting into the walls of the opening to hold the plugagainst revolution. The end of the screw is tapped into the plug at l9and when the screw is turned in toward the door panel the plate 12 willbe turned down to a horizontal position with one end fitting within thegroove 8 in the sash while the other end, bearing on the web 11, willbend it slightly sothat it will have the effect of a spring for takingup any lost motion and causing the sash to be drawns'nugly against therab'oeted edge of the stile and be held thereon with a yieldingpressure. When the screw is turned in the other direction, the plate 12will be swung to avertical position and be disengaged from the grooves 8and thereupon the sash maybe removed from the door. This web 11 formedin the door stile provides an inexpensive and convenient means fortaking up the wear of the walls of the grooves in the screen or stormsash panels, or expansion or contraction thereof due to atmosphericconditions, the pressure on the web being increased or decreased toobtain any slight variation in the position of the locking plate withrespect to its groove in the sash.

, The storm sash and the screen being interchangeable, one may besubstituted for the other and by a simple movement of the locking screwsthe plates 12 may be swung to their locking position in the sash or thescreen, and the substitution of the screen for the storm sash easily andquickly e'ifected without the use of any other tools except an ordinaryscrew driver. The looking plates will be invisible when mounted in thedoor and the ornamental head 16 will present a neat, finished appearanceto the outside of the door and be the only indication on the outside ofany fastening means for the sash or that it does not form a permanentpart of the door itself.

I claim as my invention:

1. The combination, with a door having a removable panel and rabbetededges against which said panel is seated and a stile having a verticalgroove therein, said panel having a corresponding groove adapted toregister with the groove in the stile when the panel is seated therein,said stile having an opening extending transversely of said groove, ascrew fitting within said opening, a plate having means for interlockingwith the shank of said screw for revolution therewith, the end of saidplate projecting into the groove in said panel when the screw isrevolved and said plate having a yielding backing in said stile grooveresisting pressure of said screw to seat said plate against the wall ofsaid panel groove and compensate for expansion or contraction of thewood.

2. The combination, with a door having a removable panel and a seatformed in the door stiles to receive said panel, said stiles havinggrooves in their inner edges and said panel having corresponding groovesto register therewith, plates fitting within the grooves in said stilesand having key-hole slots near the middle portion thereof, said stileshaving holes extending therethrough transversely of said grooves, screwsfitting within said holes and within the slots in said plates and havingmeans for interlocking with said slots for revolving said platessimultaneously with said screws, the ends of said plates projecting intothe grooves in said panel for pressing the panel against the seats insaid stiles when said plates are revolved.

3. The combination, with a door stile having a seat for a removablepanel and provided with inner and outer recesses and a yielding integralweb between them, of a plate mounted in one of said recesses and adaptedto be moved from an upright position therein to a horizontal position toengage the door panel, and means for moving said plate andsimultaneously flexing said web to hold said panel toward its seat witha yielding pressure.

The combination, with a door having a removable panel and a seat formedin the door stiles to receive said panel, said panel having grooves inits edges and said stiles having grooves arranged in pairs with websformed between them, one groove oi each pair normally registering withthe opposite groove in the panel when the door and panel are assembled,plates fitting within grooves in the stiles and seated against the webstherein, one end of the plates being adapted when revolved to enter thegrooves in the panel and means passing through said plates and webs forflexing said webs and clampin said panel in said stiles.

5. The combination with a door having a removable panel and a seatformed in the door stiles to receive said panel, said panel having sawslits in its edges forming narrow grooves and said stiles having sawslits in their edges arranged in pairs with yielding webs formed betweenthem, the grooves of said panel being opposite the grooves in saidstiles and onegroove of each pair in the stiles being normally inregister with the opposite grooves in the panel, plates mounted torevolve in one of the grooves in the stiles and having ends to enter thegrooves in the panel, and means for revolving said plates and pressingthem against said webs to flex the same and clamp said plates againstthe walls of the panel grooves.

6. The combination, with a door having a remo able panel and a seatformed in the door stiles to receive said panel, said panel havinggrooves in its edges and said stile having grooves in its edges adaptedto register with the grooves in said panel, plates fitting within thegrooves in said stiles, plugs mounted in sockets in said stilestransversely to the grooves therein, screws fitting within said socketson the opposite side of said stiles and having one end tapped into saidplugs and provided with means for engaging said plates to revolve thesame when said screws are revolved, the heads of said screws beingwithin said sockets and partially concealed by the walls thereof,revolution of said screws engaging one end of said plates with the wallsof the grooves in said panel.

In witness whereof I have hereunto set my hand this 29 day of May, 1918.
